CARBON-REMOVING AND LUBRICATIN G ATTACHMENT FOR IN TERNAL-COMIBUSTIONENGINES.

Specification of Letters Patent.

Patented Dec. 16, 1919.

Application filed April 10, 1919. Serial No. 289,007.

To all whom it may concern:

Be it known that I, Jnssn W. SILVER, a citizen of the United States,residing at South Tacoma, in the county of Pierce and State ofWashington, have invented new and useful Improvements in Carbon-Removingand Lubricating Attachments for Internal Combustion Engines, of whichthe following is a specification.

This invention relates to means for improving the operation of internalcombustion engines by supplying thereto a carbon removing andlubricating vapor and thereby cleaning the cylinders of gasolenc oranalogous internal combustion engines or motors and materiallyeconomizing in the use of gas in the operation of the engine or motor.One of the principal objects oi the invention is to provide anattachment that may be readily applied to gasolene engines ofautomobiles or other vehicles and also to stationary gas engines Withoutrequiring any essential modification in the construction and arrangementof the parts of the engine and whereby a cleaning and lubricating vapormay be automatically supplied to the manifold of a asolene or internalcombustion engine and distributed throughout the series of cylinderscomprised Within the engine structure. With this and other objects andadvantages in View, the inven tion consists of the construction andarrangement of the several parts which will be more fully hereinafterdescribed and claimed.

In the drawings:

Figure 1 is an elevation of a portion of an internal combustion engineof the type usually employed in automobiles and showing intake andexhaust manifolds and a part of the dash of an automobile with theimproved attachment applied thereto, and mainly shown in transversevertical section.

Fig. 2 is a transverse vertical section taken in the plane of the line22, Fig. 1.

Fig. 3 is an enlarged horizontal section taken in the plane of the line33, Fig. 1.

The numeral 5 designates a container which is preferably formed of glassand supported by a band or clip 6 which is clamped around the saidcontainer and secured to the dash 7 b a suitable fastening means, as at8. The and or clip 6 will be first secure-d to the dash and thecontainer 5 subsequently inserted therein and secured, the said cliphaving angularly projecting ends 9 engaged by a clamp screw 10 wherebythe said ends 9 may be drawn closely together to clamp the band or cliparound the body of the container and reliably hold the latter in appliedposition. The container 5 has an upper reduced neck 11 which iscorrugated or threaded to receive a chamber cap 12 and a horizontalpartition plate or disk 13 which is firmly held in place on the upperend of the said neck within the lower portion of the chamber cap 12. Thepartition disk 13 practically forms a bottom for the chamber cap 12 andhas a central depending tube 14 with a perforated flanged disk 15 at itslower end. On the tube 14 a short distance below the partition disk 13is a perforated flanged disk 1(3,similar to the disk 15. The tube 14with the disks l5 and 16 and the partition disk 13, as well as thechamber cap 12, are all formed of metal or other suitable material of anon-corrosive nature, and within the chamber cap 12 is a mixing chamber17 of materially less diameter than the cap and whereby a passage 18 isformed between the mixing chamber and the cap, the passage 18 beingobstructed in its complete continuity by depending flange 19 extendingfrom one vertical wall of the chairs ber 17 downwardly to the partitiondisk 13. From the bottom of the mixing chamber a short length tube 20extends and continuous through the partition disk 13, said tubeterminating above the perforated flanged disk 16. The chamber cap 12 hasa top inlet 21 with a removable cover 22 fitted thereover for fillingpurposes. Connected to the upper portion of the mixing chamber 17 is atube or pipe 23 which extends through or across the passage 18 andoutwardly through the adjacent wall of the chamber cap 12 and in partlies along and close to the exhaust manifold and is also connected tothe intake manifold 24 as at 25, the pipe 23 having a valve 26 thereinadjacent its point of attachment to the intake manifold for eontrollincommunication of the mixing chamber 1% with the said manifold. Attachedto and opening through the chamber cap 12 and communicatin with thepassage 18 just above the obstructing or baflie flange 19 is a pipe 27which extends along in engagement with the exhaust manifold 28.

oil being first prepared before depositing the same in the container.This combination of oils is supplied through the inlet 21 and passesdownwardly through the chamber cap 12 to the upper end of the pipe 14;and then through the latter into the container and after the containerhas thus been supplied with the combined oils, the motor or engine, ofwhich the manifolds 24; and 28 form parts, is started into operation andgraduall slowed down, the valve 26 being closed w en the motor or engineis started. After the motor or engine has been suitably slowed down,orits running 'speed materially reduced, the valve 26 is opened and thesuction of the motor or engine is ermitted to operate through the pipe23. his suction of the engine or motor acting through the pipe 23 drawsthe air out of the mixing chamber 17 and causes the formation of apartial vacuum in the said chamber and creates a suction through thetube 20 relative to the contents of the container 5 and the outside airat the same time is drawn through thepipe 27 3 into the passage 18, thisair, as will be understood, being heated. The hot air drawn into thepassage way 18' through the pipe 27 is forced to pass upwardly over anddown around the mixing chamber 17 by reason of the' baflle orobstru'cting flange 19 and by this means the said mixing chamber-isthoroughly heated. The heated air from the passage 18 continuesdownwardly through the pipe 14: and is delivered close to the bottom 0the container 5 and then passes upwardly through the lower flangedperforated disk 15 which operates to divide the air into minutecurrents. These currents of heated air are drawn upwardly through thecombined oils in the container 5 which causes the said combined oils toevaporate. The air currents ladened with the va rized oils then pass uwardly through t e erforated disk 16, t .e latter actin as asp ash toprevent 50 the air from'tfirowing the 011 in bulk upwardly into themixing chamber 1'7. After passing through the perforated disk 16 the oilladen hot air currents then enter the said mixing chamber through theitnbe 20 which is materi heated and sheets a thorough mixture the airand oils. From the mixing chamber the vaporized oils and the air passout through the pi 23 and are further heated and more comp etely vaorized by the heated part of this pipe and t en conducted down tothexintake manifold 24 "whichstill further heats the mixture and createsa gas which unites with the gasolene gas after the latter haspassedthrough the usual form of and'at the same time a greas lubricant iscarried into the cylinders an caused to engage the pistons of the motoror .engine with said gasolene gas and by this means in combination withthe usual lubricating or oiling system, the pistons are thoroughlylubricated. The vaorized coal or kerosene oil that is carried mtothemanifold with the hot air and mixed with the gasolene gas serves as acylinder cleaningmedium and also as an effective decarbonizmg agent andwhereby the carbon deposits within the cylinders and adjacent partsareremoved and caused to pass out through the exhaust. The cleanin ordecarbonizing element also serves to fieep the spark plug heads incleanly condition with material advantage in the operation of the same.In addition to removing the carbon from the cylinder walls, it will alsobe understood that the pistons are relieved of carbon dc osits. The pipe27 is held in connection with the exhaust manifold as shown by means ofa suitable clamp 29, and the heat of this exhaust manifold istransmitted to the pipe and the air drawn through the latter iscorrespondingly tempered or heated.

From the foregoing it will be seen that the improved attachment may bereadily applied to any type of automobile or other veicle motor orengine by simply securing the band or clip 6 to a support at a suitabledistance from the intake and exhaust manifolds and connecting up thepipe 23 to the intake manifold and securing the pi e 27 against theexhaust manifold. It w' also be understood that the container 5 willhave a suflicient capacity to render the operation thereof effective andit is proposed to modify the proportions, dimensions and general detailsof construction within the scope of the appended claims to adapt theimproved attachment for various applications.
